As we know vacuum mean the the pressure is maintained below atmospheric pressure( unit : mm Hg ).So the manufacture made a research and development to design the vacuum circuit breaker based on current cannot jump in vacuum condition.

Vacuum Circuit Breaker used the vacuum pressured to extinguish the current arc when it switching.Normally this type of circuit breaker used for medium voltage ( 1 – 35 kV ) power supply.The ampere rating for vacuum circuit breaker is until 3000 ampere.

Vacuum Circuit Breaker have a high insulating strength and capable to extinguish the current arc for medium voltage power supply.It more safe for switching and environment friendly.It only a vacuum atmosphere. read more
